Mine is a minor voice, Doug....
Dead? I was in Walmart once...about 12 years ago in N. Carolina, when I needed a small cooler. This was before I knew much about them, but already didn't like the way local businesses disappeared when they arrived. That Walmart was the ONLY choice in that town.

I don't 'study' every business to see if they comply with my political views, but I do note when one gets to be rather famous...or rather, infamous....for exceeding the bounds of my ethical views.

I'm not likely to affect their fortunes by either my posts OR my shopping habits. But I will say that I am quite willing to pay a bit more to do my small part to support a business that is NOT engaged in predatory marketing.
And, yes...I make a serious distinction between my political & ethical views, though they often lead to similar opinions.
